A confined space refers to any enclosed or partially enclosed area in the context of mining that is not designed for continuous occupancy and may have restricted entry or exit.
Examples in mining operations include tanks, silos, storage bins, hoppers, vaults, and pits. The nature of these spaces makes them inherently hazardous, and they require specialised knowledge and precautions to be managed safely(Confined Spaces in Mining | Mine Training Australia, 2024).
Below are some safety tips to work in confined spaces:
- Conduct a Risk Assessment: Assess the hazards of a confined space before entry. Identify risks and determine the necessary controls to mitigate them.
- Ensure Proper Ventilation: Maintain adequate airflow to prevent the buildup of hazardous gases and maintain oxygen levels.
- Use the Right Equipment: Workers should be equipped with personal protective equipment (PPE) such as helmets, gloves, respirators, and safety harnesses.
- Monitor the Atmosphere: Utilise gas detectors to regularly monitor air quality, ensuring it is safe for entry.
- Develop and Follow Entry Permits: Implement a confined space entry permit system to document and control all activities within the space.
- Appoint a Safety Attendant: Station a trained attendant outside the confined space to monitor and assist the worker inside.
- Emergency Preparedness: Have an emergency response plan in place, including rescue procedures and readily available rescue equipment((Safety Tips for Confined Space, 2025)).
